That means, there’s no longer a .mp4 file. Instead, it’s now a .m3u8 file (aka “Playlist”) that has been chopped up into a number of smaller chunks – aka “segments” – basically multiple, partial pieces of the video, which have the .ts file extension.

On top of that, the stream has been encrypted using industrial-strength AES 128-bit Encryption. Which means, even if someone, somehow manages to download the video segments, and tries to manually put them together, or uses some slick video downloading software like Internet Download Manager (IDM) or a browser extension like VideoDownloader, they won’t be able to play the video.
